Haha didn't even notice that. Now when i change it to ss[0], i get 

Error 1 Cannot implicitly convert type 'Autodesk.AutoCAD.DatabaseServices.DBObject' to 'Autodesk.AutoCAD.DatabaseServices.Entity'. An explicit conversion exists (are you missing a cast?) C:\Users\user\Dropbox\Programming\Cad\Cad\TheProgram\Drawing Commands\Copy of AREA.cs 28 27 Commands

if (ss.Count > 0)
{
ent = acTrans.GetObject(ss[0].ObjectId, OpenMode.ForWrite);
ent.Erase();
}
acTrans.Commit();

Scratch that, fixed it

public void EraseObj()
{
Document acDoc = Application.DocumentManager.MdiActiveDocument;
Database acCurDb = acDoc.Database;
Editor ed = Application.DocumentManager.MdiActiveDocument.Editor;

using (Transaction acTrans = acCurDb.TransactionManager.StartTransaction())
{
PromptSelectionResult acSSPrompt;
acSSPrompt = ed.SelectLast();
Entity ent;
SelectionSet ss = acSSPrompt.Value;

if (ss.Count > 0)
{
ent = acTrans.GetObject(ss[0].ObjectId, OpenMode.ForWrite) as Entity;
ent.Erase();
}
acTrans.Commit();
}
}
}
}

Thanks a million for your help!

Hi,

Glad to help you, sorry the mistake, i feel much comfortable with vb 'cause I'd like to see "End this", "End That"... instead of a lot of brackets at the end of a block of code.
